Asking Allah for guidance and piety
Abdullah bin Mas’ud (radi Allahu anhu) reported that the Prophet (sal Allahu alaihi wa sallam) used to say: “Allahumma inni as’alukal-huda wat-tuqa wal-`afafa wal-ghina (O Allah! I ask You for guidance, piety, chastity and self-sufficiency)”
This Hadith contains four words, the meanings and implications of which constitute its essence. These words are guidance, piety (fear of Allah), chastity and sufficiency.
Guidance here means guidance at every turn of life and steadfastness on the path of truth.
Fear of Allah is the greatest means of piety and strongest defense against sins.
Chastity is the state of being free from what is unlawful.
Self-sufficiency is the antonym of poverty and here it means the self-contentment. What it implies is that one should not care for what people possess.
In view of all these qualities, the prayer of the Prophet (sal Allahu alaihi wa sallam) mentioned in this Hadith is very comprehensive and valuable.
And Allah Knows Best!
